Definitions
- the present invention relates to a device for maintaining and controlling a part.
- the invention also relates to the application of such a device in particular to the attachment of a part on a part of the body of a motor vehicle.
- a clamping device In order to fix accurately a piece for example sheet metal on a part of the body of a motor vehicle, a clamping device is used which keeps it clamped between a movable support member and a fixed support member.
- a device is used. which is distinct from the clamping device above.
- the object of the present invention is to overcome this disadvantage.
- a device for holding a workpiece comprising a first movable support member with respect to a second fixed support member towards a clamping position in which a part of said workpiece is clamped. between said first and second support members, along a first axis, characterized in that it further comprises a movable control member along a second axis different from or identical to the first axis, towards an indexing position in which said member pilot is engaged in a hole made in said part and an actuator for simultaneously controlling the displacement of said first support member to said clamping position and the displacement of said control member, to said indexing position.
- the device makes it possible to perform two functions simultaneously, namely keeping the workpiece in position by clamping along a first axis and driving this workpiece along a second axis.
- the cost of such a clamping device and control is less than the total cost of a clamping device and a separate control device and is much more convenient use than the latter, while allowing to reduce the durations mounting parts.
- said actuator is a jack whose body is fixed and the rod is movable in translation along an axis parallel to said first axis.
- the rod of the cylinder is connected firstly to a first transmission assembly for moving the first support member to said clamping position and secondly to a second transmission assembly allowing move the control member to said indexing position.
- said first transmission assembly comprises a transmission element extending parallel to the rod of the cylinder, one end of which is fixed to this rod and the other end of which carries a pivot axis of a first lever hingedly connected to a second lever which is itself connected to the first support member which is pivotally mounted along an axis, between a position spaced from the second support member and a position in which said part of the part is clamped on the second support member by the first support member.
- said pivot axes are perpendicular to a plane containing said first and second axes.
- said second transmission assembly comprises a transmission element extending parallel to the rod of the cylinder, one end of which is fixed to this rod and whose other end carries a pivot axis of a lever connected in an articulated manner. along a pivot axis fixed to another lever which is itself hingedly connected to said control member.
- said control member is mounted in translation along said second axis in a fixed guide.
- the pivot axis which connects said transmission element and said lever is guided by an arc-shaped light made in a fixed part relative to said lever.
- control member may be a rod whose end intended to engage in the hole of said piece is pointed.
- the invention also relates to the application of the device according to the invention, to the attachment of a part to a part of the body of a motor vehicle.
- FIG. 1 is a diagrammatic elevational view of a clamping and driving device according to the invention, in an inactive position, before placing the workpiece in place,
- FIG. 2 is a view similar to FIG. 1, the part being in the clamping position and the control member being in the indexing position,
- FIG. 3 is a perspective view of a device according to the diagram of Figure 1, the piece being in place ready to be indexed on another piece.
- FIGS. 1 and 2 schematically represent a device for holding and controlling a workpiece 1 (see FIG. 2) comprising a first support member 2 movable relative to a second fixed support member 3, towards a clamping position ( see Figure 2) wherein a part 1 of the part 1 is clamped between the first and second bearing members 2, 3 along a first axis A1.
- the device further comprises a control member 4 movable along a second axis A2 perpendicular to the first axis A1, towards an indexing position in which (see FIG. 2) the control member 4 is engaged in a hole 5 made in the Part 1b of Exhibit 1.
- the device also comprises an actuator 6 for simultaneously controlling the displacement of the first support member 2 towards the clamping position, shown in FIG. 2, and the displacement of the control member 4 towards the indexing position also represented on FIG. Figure 2.
- the actuator 6 is a jack whose body 7 is fixed relative to a support (not shown) and the rod 8 is movable in translation along an axis parallel to the first axis A1.
- the rod 8 of the jack 6 is connected on the one hand to a first transmission assembly 9 for moving the first support member 2 to the position clamping and secondly to a second transmission assembly 10 for moving the control member 4 to the indexing position.
- the first transmission unit 9 comprises a transmission element 1 1 extending parallel to the rod 8 of the cylinder 6, one end of which is fixed to this rod 8 and the other end of which carries a pivot axis 12 of a first lever 13 hingedly connected at 14 to a second lever 15.
- This lever 15 is itself connected to the first support member 2 which is pivotally mounted along a fixed axis 16 between a position spaced apart from the second support member 3 (see FIG. 1) and a position in which the part 1 has the piece 1 is clamped by the first support member 2 on the second support member 3, as shown in Figure 2.
- the pivot axes 12, 14 and 16 are perpendicular to a plane containing the first and second axes A1 and A2.
- the second transmission assembly 10 comprises a transmission element 1 1 extending parallel to the rod 8 of the jack 7.
- One 17a of the ends of this transmission element is fixed to the rod 8 and the other end 17b carries a pivot axis 18 of a lever 19 connected in an articulated manner along a fixed pivot axis 20 to another lever 21 which is itself hingedly connected at 22 to the control member 4.
- This control member 4 is mounted in translation along the second axis A2 in a fixed guide 23.
- the pivot axis 18 which connects the transmission element 17 and the lever 19 is guided by a circular arc-shaped light 25 made in a part of the device which is not shown.
- the arc of this light is centered on the pivot axis 20 of the lever 19.
- control member 4 is a rod whose end intended to engage in the hole 5 of the part 1 can be pointed.
- FIG. 3 represents a concrete embodiment of the device shown diagrammatically in FIGS. 1 and 2.
- the common parts between Figure 3 and Figures 1 and 2 are designated by the same reference numerals.
- FIG. 3 shows in particular that the light 25 is produced in a part 26 which carries the pins 18, 20 and 22 and thus forms the lever 19 represented in FIGS. 1 and 2.
- the movable support member 2 carries the axes 14 and 16 and thus forms the lever 15 shown in FIGS. 1 and 2.
- the entire device shown in Figure 3 is contained in a not shown housing which serves to support all the fixed parts of the device, namely the body 7 of the cylinder 6, the fixed support member 3 and the axis fixed pivoting 20.
- the inverted L-shaped piece 1 is in position on the device, the part 1a of this part being supported by the fixed support member 3.
- Part 1b of part 1 is applied to part 27 of the body of a motor vehicle on which it is desired to fix part 1.
- the pivoting of the movable support member 2 towards the fixed support member 3 makes it possible to clamp the part 1a of the part 1 between these two members, that is to say to hold it in position relative to to the device.
- control member 4 makes it possible to control the piece 1, ie to index the hole 5 of this piece 1 with respect to another hole, not shown in the figures, made in the part 27 on which piece 1 must be fixed.
- the invention can be applied to other fields than the automotive industry.
